Repeat Character String N Times in R

In this article, we will discuss how to repeat the character string N times in the R programming language. Character string means a set of characters .

Example:

"Hello Geek","Python","Languages_Python" are some examples

Method 1: Using replicate() method

This function used to give n replicas from the character string

Syntax:

replicate(N, "string")

where,

• N is the number of times string is replicated
• string is the input character string

Example: R program to repeat the character string N times using replicate

 
 

Output:

 

[1] "Hello_Geek" "Hello_Geek"

[1] "-----"

[1] "Python" "Python" "Python" "Python" "Python" "Python" "Python" "Python"

[9] "Python" "Python"

[1] "-----"

[1] "java" "java" "java"

[1] "-----"

[1] "dbms" "dbms" "dbms" "dbms"

[1] "-----"

[1] "sql" "sql" "sql" "sql" "sql"

[1] "-----"

[1] "big data" "big data" "big data" "big data" "big data" "big data" "big data"

Method 2: Using rep() method

 

This function works similar to replicate .

 

Syntax:

 

rep( "string",N)

 

Example: R program that repeats character String N times using rep

 

Output:

[1] "Hello_Geek" "Hello_Geek"

[1] "-----"

[1] "Python" "Python" "Python" "Python" "Python" "Python" "Python" "Python"

[9] "Python" "Python"

[1] "-----"

[1] "java" "java" "java"

[1] "-----"

[1] "dbms" "dbms" "dbms" "dbms"

[1] "-----"

[1] "sql" "sql" "sql" "sql" "sql"

[1] "-----"

[1] "big data" "big data" "big data" "big data" "big data" "big data" "big data"

Method 3 : Using paste along with replicate

This paste is used to organize the repeated strings in the correct way, It will separate the strings with the given delimiter.

Syntax:

paste(replicate(N, "string"), collapse = "delimiter")

where,

• paste is used to display the data
• replicate is used to get the N character strings
• collapse is used to separate the strings

Example: R program to repeat the character strings using paste command

Output:

[1] "Geek--Geek"

[1] "-----"

[1] "Python,Python"

Method 4: Using strrep() function

This function is used to get the N character strings in a single string.

Syntax:

strrep( "string",N)

Example: R program to get N character strings using strrep() function

 
 

Output:

 

[1] "Hello_GeekHello_Geek"

[1] "-----"

[1] "PythonPythonPythonPythonPythonPythonPythonPythonPythonPython"

[1] "-----"

[1] "javajavajava"

[1] "-----"
